Replace A Single Line Of Text In Multiple Files On Mac OSX

Earlier I was transferring some configuration files from an application on a Windows 7 computer to an application on a OSX Lion computer. The location of a file referenced in the configuration files had changed so I needed to update about a hundred different INI files with the new location. Doing this on OSX is very easy using perl as long as you get the syntax correct as it can be tricky if there are multiple quotes and or slashes. Below is a quick example of a perl command used to replace a single line of text in multiple files without having to modify each file individually.
